A cold compress is a frozen or chilled material, such as an ice pack or a cooled washcloth. There are different types, including homemade and commercially available products.
Cold compresses can be used to manage swelling and inflammation. They may even help manage bleeding. Cold restricts blood circulation to numb pain and reduce bruising.
You have different options for the types of cold compresses you can use based on the type of injury. For example, you can use an ice mask for sinus or eye pain or an ice pack after a minor fall.
How to Make a Cold Compress
Various types of cold compresses are available for purchase at your favorite retailer. Some are specially designed bags that you can fill with ice at home, and others are chemical packs that, when broken, will freeze.
You can also make your own cold compress at home. Some homemade cold compresses include ice as a main ingredient. Ice is the most effective way to manage swelling from an injury.
To make an ice-based instant cold compress:
- Use a clean, sealable bag.
- Fill it with ice.
- Wrap the bag in a thin cloth or paper towel to protect the skin.
- Apply to the injury.
You can also freeze a wet washcloth or towel to make a homemade compress.
- Dampen the washcloth or towel.
- Wring out any excess liquid.
- Seal the cloth in a bag.
- Freeze the bag until it is solid.
- Wrap the bag into a light cloth or paper towel.
- Apply to the injured body area.
To make a cold compress using frozen vegetables:
- Use small frozen vegetables, such as peas, corn, and mixed vegetables.
- Put a small amount of frozen vegetables in a plastic resealable bag.
- Cover the bag with a clean towel and apply it to the affected area.
The RICE Method
When applying a cold compress to an injury, consider using the RICE method. “RICE” stands for “rest, ice, compression, and elevation.” The RICE method should be started as soon as you notice pain and swelling in the injured area.
How to Use a Cold Compress
Headaches
For a headache, you may apply a cold compress to your head or neck for a numbing effect. Apply a cold to the painful, tense area for 20 minutes at a time every four to six hours. You may also consider an ice massage to manage headache pain. Massage the affected area with an ice cube or ice pack in a circular motion for up to five minutes.
Eyes
For the eye, you need to be careful about the kind of cold compress used and for how long. Commercial cold packs are often too cold to use on the eye. A washcloth dipped in cold water is often enough. You can also wrap a small bag of ice cubes in a small towel.
Do not use a cold compress on the eye for too long. The Rand Eye Institute recommends using a cold compress on the affected eye for no more than 20 minutes at a time. For swelling, you can reapply every two hours.
Fevers
To manage a fever, place a cooling cloth or ice pack on the forehead. For very high fever, place the ice pack under the armpit or groin area where there are larger blood vessels. Wrap the compress in a towel to avoid direct skin contact. Leave the pack in place for no more than 15 minutes and move it consistently to prevent frostbite.
Babies and Small Children
Do not use cold compresses on babies or small children. They cannot tell you if the pack is too cold and injury may result.
Pain Management
Cold compresses can help manage pain, swelling, and symptoms associated with acute (sudden, short-term) injuries, gout, muscle strains, and tendinitis (tendon irritation). For these conditions, you can use an ice massage or cold pack for 20 minutes on and 30 minutes off.
Nosebleeds
You can use a cold compress to slow or stop a nosebleed. If a nosebleed has not stopped after 15 minutes, try placing a cold compress on the bridge of the nose and pinching the nose shut.
How Long and How Often to Apply Cold Compress Therapy
Apply ice for no more than 20 minutes at a time. After waiting 30 minutes, repeat. Icing for 20 minutes several times a day manages swelling and pain, and it may control inflammation and swelling better than oral pain medicines and injections.
Benefits of Cold Compresses
Benefits of using compresses on the body include:
- Brings down fever: Cold can reduce body temperature. Apply compresses to the areas of the body that have blood veins close to the skin surface.
- Heals bruises or cuts: If you have recently had an injury that left a bruise or a cut, a cold compress can reduce swelling and speed up healing.
- Manages chronic headache pain: A cold compress can help soothe a headache by reducing tense muscles in the forehead, face, back of head, neck, and back. However, a new headache should be evaluated by a healthcare provider, especially if you have a fever and headache.
- Reduces inflammation: Cold compresses can reduce swelling and pain caused by inflammation. Cold treatment can reduce blood flow to an injured or inflamed area, reducing swelling and risk of tissue damage.
- Soothes sore muscles: Cold compresses can reduce pain related to painful muscles. Cold can also function as an anesthetic to numb sore areas and slow down pain messages that are being transmitted to the brain.
- Treats muscle spasms: A cold compress can ease the discomfort of muscle spasms by relaxing tight muscles and easing cramping.
- Manages eye symptoms: Cold compresses can relieve symptoms of various eye conditions. They can be used to manage swelling, itch, and redness related to allergies, dry eye, and pain related to eye injuries.
- Stops bleeding: Cold can constrict blood vessels to slow or stop bleeding. For example, the compress’s coldness can narrow the nose’s tiny blood vessels and help stop a nosebleed.
Risks and Warnings
Cold compress therapy is a safe and powerful way to manage pain and swelling and effectively promote healing. However, it should be used correctly.
You should avoid cold compresses if:
- There is a risk for cramping, which can be worsened by cold.
- The affected area is already cold or numb.
- There is an open wound, or the skin is blistered.
- You have a vascular disease or nerve disorder that affects blood flow.
- You are sensitive to cold or have a condition that causes decreased sensations, such as diabetes or Raynaud’s syndrome (blood vessels constrict, reducing blood flow to the fingers and toes).
When using cold therapy, you will want to avoid:
Direct Skin Contact With the Ice
Do not apply ice or a cold compress directly to the skin. This can cause frostbite, a skin injury due to exposure to freezing temperatures. Wrap your cold compress in a towel or cloth to provide a barrier between your skin and the ice.
Using for Long Periods
You should avoid prolonged exposure to cold temperatures, as this can lead to tissue damage. To prevent adverse reactions, limit your cold therapy sessions to no more than 20 minutes.
Contraindications
Cold therapy is not suitable for everyone, including people with vascular and nerve diseases and who are sensitive to cold temperatures. Consult your healthcare provider before using cold compresses if you have an underlying health condition.
If the cold compress is too uncomfortable or painful, stop using it or adjust it so it is comfortable.
Warm vs. Cold Compresses
Warm compresses may help to relieve pain, strains, and irritation. They can be dry or moist.
Dry heat therapy includes heating pads, while moist heat therapy includes steamed towels and hot water bottles. You can purchase heating pads or hot water bottles from your favorite retailer or make your own warm compress. Wrap a hot compress in a towel or thick cloth to avoid burning the skin.
Use warm compresses to manage stiffness and tension for 15 minutes at a time, with 30 minutes off.
Some people should not use warm compresses. This includes people with:
- Bruising or open wounds
- Deep vein thrombosis
- Dermatitis
- Severe memory problems
You should also check with your healthcare provider on the safety of warm compress therapy if you have high blood pressure (hypertension) or heart disease. These conditions can impair the body’s ability to increase blood flow and sweat in response to heat.
If you experience muscle or joint pain that lasts more than a few days, make an appointment with your healthcare provider.
Deciding Which One to Use
Cold compresses are helpful for acute (sudden, short-term) injuries, inflammation, and swelling. Cold can slow blood flow to the injured area to reduce pain and swelling.
Heat can be helpful for chronic (long-lasting) pain conditions, such as arthritis, overuse injuries, and those that occur over time. Heat can increase blood flow to repair damaged tissues.
Some injuries and health conditions may benefit from alternating between cold and hot compresses. Apply ice for no more than 20 minutes at a time and wait at least 30 minutes before icing again.7
After icing the area for 48 hours, you can apply heat. Use heat for 20 minutes at a time.
Sinus pain and pressure can be alleviated by alternating between cold and warm compresses. Warm compresses can help warm nasal passages to loosen mucus, while cold compresses can help reduce sinus pressure.
Where Are the Sinuses Located?
The sinuses are air-filled cavities found in the skull bones. They are named based on their location and include:
- Ethmoid sinuses: On each side of the bridge of the nose, near the eyes
- Frontal sinuses: Over the forehead and above both eyes
- Maxillary sinuses: Over the cheek area, under the eyes on both sides of the face
- Sphenoid sinuses: In the sphenoid bone located at the center of the skull, just behind the eyes.
You can start by placing a warm washcloth across the inflamed sinuses for about three minutes. Remove the warm compress and place a cold compress across the same area for 30 seconds. Alternate two to three more times and repeat up to four times a day.
For other conditions, the rule is to apply cold first to reduce swelling. Once the swelling goes down, you can use heat for pain relief and to promote blood flow to allow the body area to heal. The type of injuries where you should start with ice and then heat later are:
- Back pain
- Knee pain
- Muscle soreness
- Neck pain
- Pulled muscle
- Shoulder pain
- Tendonitis or bursitis
